Private, peaceful island living

Welcome to Key Biscayne

Key Biscayne, situated just south of Miami, Florida, is a beautiful island town home to around 12,800 residents. With a relaxed and laid-back atmosphere, the island offers stunning views of beaches and a tropical environment. It's almost like living in a private country club, with the added benefit of a fire department and police force. 

Residents commonly get around in golf carts; everything is close since the island spans just one square mile. The schools are terrific, and there are many fantastic lifestyle activities to enjoy, such as tennis, golfing, and sunbathing on the beaches. Plus, the sense of community is strong  — there's always something on the calendar to bring everyone together and celebrate. Why miss the city when life in Key Biscayne feels like a resort?
